ECU compatibility

[DesmondGhostRider]

ECU still doesn't have power.

I bought new relays that are the proper spec and installed them. I checked all the fuses under the dash and in the engine bay. Still no power. Battery was a little low from sitting with lights on so I threw a charger on it. No power to pins A12 or A13. I replaced diode.

Still no engine light or power to the pins to power it.

I took readings from the relays. I didnt think to write down the colors, but I wrote them out as 1, 2, 3, 4. 1- Top Left, 2 - Top Right, 3 - Bottom Left, 4 - Bottom Right. The top is indicated by the tap facing upward.

Green - Pump
Key On
1. Positive - 13.63v
2. Negative - 14.46v
3. Positive - 13.69v
4. Negative 14.14v

Key Off
1. Negative - 14.38v
2. Negative - 14.38v
3. Negative - 14,38v
4. Negatie - 14.38v

White - Main
Key On
1. Positive 13.89v
2. Positive 14.10v
3. Positive 13.92v
4. Negative 14.09v

Key Off
1. Negative 14.38
2. Positive 14.36
3. Negative 14.38
4. Negative 14.32

I'm guessing its
1. Constant
2. Switched
3. To Device
4. Ground

It looks like there might be some slight leaking on my C103 Capacitor. I'm going to get that swapped out tomorrow.

I might try soldering another diode in D102 to make sure it wasnt just damaged or something. The pack I bought came with 2.
